positive: - fair price, durability, super protection in the event of a fall (in my regular), relatively neutral odor (barely perceptible) negative: the side buttons have to be pressed a little harder than before without cover not (is in the nature of things), the material probably technically possible otherwise the shell can be on both sides of your smartphone a two millimeter square, that is in my current construction activity that some dirt between casing and mobile phone comes (was now however not surprising) but you should point out at least -> Conclusion: good four star
